While the version is only 0.2, the extension is fully functionnal. It just two adds an entry to Firefox' contextual menu:- upload to uppix: regular upload to uppix.net)- upload to uppix (my pix): upload the image to uppix.net and adds it to your gallery (for registered users)Options allow you to choose whether you prefer the uppix.net page to open in the same window, a new tab, a new window, or in a new tab without focus.

Thanks to Balrog for giving me the idea and to the picscrazy.com staff for their code ^^
